Adding a Menu Item to FlowDocumentReader ContextMenu

Question

There are two menu items in FlowDocumentReader in ContextMenu, Copy and Select All. I would like to add an additional MenuItem to it and tried this:

    private void FlowDocumentReader_ContextMenuOpening(object sender, ContextMenuEventArgs e)
    {
        flowDocumentReader.ContextMenu.Items.Clear();
        MenuItem menuItem = new MenuItem();
        menuItem.Header = "Test";
        flowDocumentReader.ContextMenu.Items.Add(menuItem);
    }

Additionally, I tried this:

    private void FlowDocumentReader_ContextMenuOpening(object sender, ContextMenuEventArgs e)
    {
        MenuItem menuItem = new MenuItem();
        menuItem.Header = "Test";
        flowDocumentReader.ContextMenu.Items.Add(menuItem);
    }

where I do not clear the items in the context menu and try to add it. None of them work.

I can create my own menu like this:

    private void FlowDocumentReader_ContextMenuOpening(object sender, ContextMenuEventArgs e)
    {
        MenuItem menuItem = new MenuItem();
        menuItem.Header = "Test";
        flowDocumentReader.ContextMenu.Items.Add(menuItem);
        e.Handled = true;
        ContextMenu menu = new ContextMenu();
        MenuItem a = new MenuItem();
        a.Header = "A";
        menu.Items.Add(a);
        MenuItem b = new MenuItem();
        b.Header = "B";
        menu.Items.Add(b);
        flowDocumentReader.ContextMenu.Items.Clear();
        flowDocumentReader.ContextMenu = menu;
        menu.IsOpen = true;
    }

And it will be displayed, but what I would like to have are the menu items "Copy" and "Select All", as well as "A" and "B".

Ideas?

xaml FlowDocument:

<FlowDocument.ContextMenu>
     <ContextMenu>
          <MenuItem Header="{Resx Copy}" Command="Copy"/>
          <MenuItem Header="{Resx SelectAll}" Command="SelectAll"/>
          <MenuItem Header="{Resx CustomCommand}" Command="{Binding CustomCommand}"/>
     </ContextMenu>
</FlowDocument.ContextMenu>

( Grant Frisken Resx Extension):)

FlowDocuments, :

<Style TargetType="FlowDocument">
    <Setter Property="ContextMenu">
         <Setter.Value>
              <ContextMenu>
                  <MenuItem Header="{Resx Copy}" Command="Copy"/>
                  <MenuItem Header="{Resx SelectAll}" Command="SelectAll"/>
                  <MenuItem Header="{Resx CustomCommand}" Command="{Binding CustomCommand}"/>
              </ContextMenu>
         </Setter.Value>
    </Setter>
</Style>
